Khloé Kardashian insists that no one in her famous family has hooked up with Bieber – despite the fact that the pop star has been linked to Kourtney and is close friends with Kendall Jenner.
On Sunday night's episode of Watch What Happens Live, host Andy Cohen asked the question on every Belieber's mind.
"Which of these sisters has Justin Bieber been with?" he said, listing Kourtney, Kendall, Kylie Jenner and "all of the above" as the reality personality's options.
"None!" said Khloé, laughing. "It would be amazing if it was all of the above, though."
And the Kocktails with Khloé host had to reference the singer's well-endowed nude photo snapped by paparazzi during a skinny-dip: "We're thankful for Justin Bieber's ... you know."
Multiple sources told PEOPLE last month that Kourtney, 36, and Bieber, 21, had a flirtatious fling, though he's since moved on with Hailey Baldwin.
Khloé, 31, also revealed which of her sisters' past and current loves she'd want to marry (Kanye West), shag (Scott Disick) and kill (Tyga).
"Oh God, this is weird," she cried. "And there's no reason why, ugh!"
Watch What Happens Live airs Sunday-Thursday at 11 p.m. ET on Bravo.
